Hello,

You can take any graduation subject you feel confident in. The humanities subjects will help you with your General studies part of the civil services exam. If you want to continue with the commerce field then there are optional subjects that can help you as your optional subject in civil services exam. The optional related to your field are:

• Commerce and Accountancy
• Economics
• Mathematics

You can take any one of these as your undergraduate subject and strengthen your optional.

All the best.
